3 Claims. (01. 30434) One object of this ladder step is to relieve therung of the ladder thus greatly facilitating the strain due to limitedbearing of a ladder rung operation of adjusting the step from one rungof under the feet ofa person standing upon a ladder the ladder toanother. It is not essential to the for an appreciable length of time.invention that the extremity ('7) be formed as an 5 Another object is todistribute the weight of enlargement of the rod and it will beunderstood 60 the operator upon the elements of two ladder that the endof the rod may be turned back upon rungs most advantageously placed tosupport such itself or any other convenient method used to weight,namely, near the side pieces of the ladder accomplish the object ofenlargement. thus reinforcing the ladder .itself.
